Be it known that I, 'WILLIAM This invention 'relates to new and useful v 'improvements insectio'nal casngs for fur-- naces`=and` the principalobject of the invention is to provide a device which nay read ily be assembled or dsassenbledjwithout the' necessity of using'screwsor bolts,

Another object of the invention isto provide a device'which will permit one' of the sections tobe removed so that any repairs ma-y be made'` to jthe furnace wthout the necessity of 'taking down theentre struc- 'WVith these and other objects in View, the invention' consstsn the novel combnaton and arr'angement of parts whch will` be ully set forth in the following specification and-'accomp anying drawings, in which Figure l is a viewin elevation illustrating v the assembled furnace casing.

I g i I Referring to the drawings, the numera-l 1 designates as'an entirety, the hood or bonnet of the .device coinprising thecylindrical able hooks 4 are Secured to the bonnet and connected to these hooks 'are chains 5,' the use of which will appear as the descrption proceeds are connected which distribute the warm air *E KAs-' noHM, a citizen` of the' United States, re-

Suitthroughout the building in which the devce i is` used. i

The upper as at ?to a stationary support such as the floor joists 'shown inFig. l. The hooks are providedcwith the levei's 8 by means ,of which the same-may beswung into the dotted line position shown in Fig; lso'that the bonnet may be' lifted from theremaining 'portion' of the casing to enable the casing and, `furnace to be removed without wholly removing` the distributing and conducting pipes. *It is intended, in practice, `to have the hooks 6 of such length that, when they are j rocked -into the dotted line position ,shown in F l, the hood will be l-ifted suf- V ficiently to-permit -bodily removal of the furnace 'from beneath this hood after 'the body` of the casing surrounding the furnace has been removed. When it is not desired to remove the furnace the hood need not be lifted, as access to the interiorof the casing may be readily obtainedby removingone or more of the detachable sections thereof, as will be readily understood. In this case, anyor all of the sections of the body of the casing 'may be 'removed independently of the -hood which is uspended by thechains 5? "The body of the furnace casing is designat'edj by the numeral 9 and comprises 'a plurality of arcuate 'plates 10, each of which isjprovid'ed eat one of its vertical edges with a suitable pocket ll'formed by bending the metal back upon itself as at 12 and then ofi' setting the edge outwardlyv and in parallel relation'as at 13 to form a cover flange for engaging the edge of the adjacent section. This Construction is clearly shown inFg. 3 and it will thus beseen that a dust proof ends of the chains 5 are connected to sutable hooks 6 whchare pivoted joint is formed between the vertical edges i In order that the adjacent edges may be a substantially V-shaped frame 15 forming the body of the clasp.: The looking lever of I the clasp is designated generally by the nu-` meral 16' and coinprises a' substantially V-shaped rame 17 the ends of the arms oi' which converge and are looped as at 18 around the bight portion of the V-shaped frame 15 and are extended to form the tongue 19 the' end of which engagesthe pocket of the adjacent section to hold the' same in place.

In order that the .upper and'loWer edg es of the sections may be properly held in positon, a suitable transverse ring. 20 is provided and is adapted to fit' Withinthe sections and each section is provided near this ring With suitable openings 21 in which the pins 22 are mounted. These pins are pro- V vided at their outer ends With the heads 23 having suitable handlesl connected thereto `While the nner ends of the pins are formed With hooks 25 for engaging the inner face of the ring. r v e e lt Will be understood that the sections may be provided With suitable door openings if so desired to enable theuser .to gain easy access to the fire box and ashpit of the furnace as in the ordinary manner..

It Will be apparenti'romthe foregoing' that in use the .device is assembled in the manner illustrated in Fig. l, and if: it is de sired togain access to theinterior of 'the' casing, it will be evident that by releasing theclamps on the vertical edges of the sectionand the turning of the handles 24 so as 'to relcase'the hooks 25 from the ring, the sections may be removed and any repai-rsnay be made tothefurnace. In case one of the sections should be injured, it ,will be readily seen that the same: may be ree moved and anew section substituted therefor Without necessitating of the taking down of the entire device. V i

It Will also be seen that When so desired the furnace may be entirely removed Without disturbing the piping by liftingthe hood l-by the movement of 'the levers 8 and after the same has been replaced, it Will be evie dent that the hood may be returned to 'its original position by movng the levers to the' position shown'in the full lines in Fig. 1.

While in the foregoing there has been shown and 'described the preferred embodiment of this nventon, itfis; to be under stood that such changes may be made in the combination and arrangement of parts as' Will fall' within the-spirit and scope of the appended claims. i

What is claimed is `l. The combnation With a furnace` casng comprising a body consisting of-aplurlity of independently removable sections, and a removable hood forsaid body, of means for elevatng and suspendingfthe hood so as' to permit said sections of the body to'be removed independently of said hood.
